Title: Injection moulded low-friction watch bearing - formed in reinforced plastics plate by symmetrical injection around core
IPC: B29C45/14
Filed: 1974-09-16
Abstract: A method of moulding a low-friction watch bearing in an opening in an already cast, reinforced plastics plate is as follows: a temporary core is introduced into the opening, so as to define the central passage for the intended bearing; the low-friction plastics to form the bearing is injected in such a way that this material spreads symmetrically around the core so that there are no forces tending to displace it. The temporary core and injection opening are pref. coaxial. Pref., as soon as the plastics forming the bearing has set, the core is withdrawn into a space clear of the bearing. The high strength of the reinforced plastics plate or similar component is combined with the low-friction properties of the bearing material cast into it. By the symmetrical introduction of the material for the latter and its symmetrical flow around the temporary core, a non-shifting arrangement is ensured leading to accurately located bearings. No drilling or similar operations are required.

Title: Filter pocket for gases, with air-jet cleaning - has lining modifying air-jet local effect, preventing post-cleaning dust emission
Inventor: GUIBET JEAN-PIERRE
IPC: B01D46/06
Filed: 1975-10-15
Abstract: A filter element for gas, partic. a pocket for sleeve of filter cloth, provided with air injection for cleaning, has an inner screen to reduce the effect of the cleaning jet of air locally. The screen may be a lining of cloth more open than the filter cloth. It may extend over (part of) the height of the filter pocket, and over (part of) the width of the base. It may be secured to the pocket, or be independent of it and held by a rigid interior frame. This increases the overall yield from the element by preventing the passage of dust through the filter cloth immediately after it has been cleaned by the air jet. The lining makes the effect of the jet more uniform.

Abstract: The electronically controlled resistor is intended as an adjusting element for control circuit. It consists of several field-effect transistors, which are selectively switchable and have their drain-source paths connected in parallel. The control is carried out via the gate-source voltage of the field-effect transistors. The channel width/length ratio is different for each field-effect transistor. The control regions of the field-effect transistors overlap, when external criteria are observed. The resistor assembly permits switching from one field-effect transistor to the other. Preferably one external criterion is the maximum permissible, non-linear portion of the channel resistance of one field-effect transistor. A switching transistor may be series-connected to each field-effect transistor.

Title: Bacon slicing machine slice carrier tilting mechanism - has sliding arm released when motor stops to swing carrier to horizontal discharge position
IPC: B26D7/32
Filed: 1976-11-10
Abstract: A bacon slicing machine has a platform (12) behind the sloping plate which supports the meat as it is carried to and fro past the rotating cutting blade.

Abstract: The overhead conveyor bridge employed in the treatment plant is used for rinsing without immersing the workpieces in a bath; and the workpieces may be suspended on jigs or treated in bulk, e.g. inside a plating barrel rotating on a horizontal axis. In the pref. plant, the hoist employed for raising or lowering the jigs or the plating barrel into a row of baths is surrounded by an enclosed hood contg. spraying nozzles using pressurised water, possibly with air, for rinsing the workpieces. The hood thus forms a rinsing unit and is connected to a recovery and/or regeneration system for treating the water used in rinsing. The system can be used with automatic or manual conveyors; it reduces the amt. of water required and also the number of treatment tanks.
